hi i keep encountering the problem of [For] and [CHR]. i've changed a new sandisk cf card and even tried formatting a few times. it may occur after taking several takes or when i turn the camera on. is it a problem with the card or my camera? thanks
try plugging it to your computer and try copying some huge files or lots of files into the card (1-2GB). if copying can be completed successfully then it may not be your card problem.
